It's a lot to cover in one post but here is a brief list some of the goodies

* Completely new Drag-Drop implementation, "the way it should be"
* Static columns can now be placed on the left OR right.
* Refactored every class, cleaned up a lot of messy CSS
* New preset manager class capable of dynamically creating new "view presets"
* Set pretty much any time resolution, 5 minutes or 12 weeks.
* Support for snapping when creating/resizing and dragging
* About 10 new examples
* Lots of bug fixes (hopefully not too many new ones)

Next 2.0 version will be based on Ext 4 (aiming for a March release) and will also feature a vertical view of the timescale.
